Method of using intravaginal device with fluid transport plates

ABSTRACT

A method of capturing bodily fluid in a mammalian body includes inserting the fluid management device into the mammalian body and transporting bodily fluid. The bodily fluid is transferred via at least one fluid transport element that is capable of interfacing with a mammalian body element to provide a substantially uninterrupted fluid conduit. The fluid conduit provides a fluid path between at least one fluid transport element and the storage element. A distal portion of the at least one fluid transport element is capable of extending away from the fluid storage element.

FIELD OF THE INVENTION

The present invention relates to methods of capturing and storing bodily fluid intravaginally and devices that may be used for such purposes. More particularly, the present invention relates to a method of capturing bodily fluid intravaginally via a fluid transport element and transporting the bodily fluid to a fluid storage element where the fluid is stored.

BACKGROUND OF THE INVENTION

Devices for intravaginally capturing and storing bodily fluid are commercially available and known in the literature. Intravaginal tampons are the most common example of such devices. Commercially available tampons are generally compressed cylindrical masses of absorbent fibers that may be over-wrapped with an absorbent or nonabsorbent cover layer.

The tampon is inserted into the human vagina and retained there for a time for the purpose of capturing and storing intravaginal bodily fluids, most commonly menstrual fluid. As intravaginal bodily fluid contacts the tampon, it should be absorbed and retained by the absorbent material of the tampon. After a time, the tampon and its retained fluid is removed and disposed, and if necessary, another tampon is inserted.

A drawback often encountered with commercially available tampons is the tendency toward premature failure, which may be defined as bodily fluid leakage from the vagina while the tampon is in place, and before the tampon is completely saturated with the bodily fluid. The patent art typically describes a problem believed to occur that an unexpanded, compressed tampon is unable to immediately absorb fluid. Therefore, it presumes that premature leakage may occur when bodily fluid contacts a portion of the compressed tampon, and the fluid is not readily absorbed. The bodily fluid may bypass the tampon.

To overcome this problem of premature leakage, extra elements have been incorporated into a basic tampon to try to direct and control the flow of fluid toward the absorbent core.

For example, U.S. Pat. No. 4,212,301. (Johnson) discloses a unitary constructed digital tampon having a lower portion compressed preferably in the radial direction to form a rigid, rod-like element, which provides a central rigidified elongated core and an upper portion left substantially uncompressed. After insertion, the uncompressed portion may be manipulated to contact the vaginal wall to provide an immediate seal against side leakage. The uncompressed portion allows for high absorbent capacity immediately upon insertion. While this tampon may allow for a certain amount of protection from bypass leakage, the uncompressed portion may become saturated before the compressed portion has a chance to expand and become absorbent.

U.S. Pat. No. 6,358,235. (Osborn et al.) discloses a “hollow” bag-like tampon that may have an interior projection made from highly compressed absorbent material. The interior projection is preferably attached to the inside surface of the head of the tampon. The hollow tampon portion may include at least one pleat in the absorbent outer surface and is soft and conformable. The tampon is not pre-compressed to the point where the fibers temporarily “set” and re-expand upon the absorption of fluid. The absorbent portions of the tampon can saturate locally, which leads to bypass leakage.

U.S. Pat. No. 6,177,608. (Weinstrauch) discloses a tampon having nonwoven barrier strips which are outwardly spreadable from the tampon surface to reliably close the free spaces believed to exist within a vaginal cavity. The nonwoven barrier strips extend about the tampon in a circumferential direction at the surface or in a helical configuration about the tampon and purportedly conduct menstrual fluid toward the tampon surface. The nonwoven barrier strips are attached to the cover by means of gluing, heat sealing, needle punching, embossing or the like and form pleats. The nonwoven barrier strips are attached to the tampon blank and the blank is embossed, forming grooves extending in a longitudinal direction. While this tampon purports to direct fluid to the core, it attempts to achieve this by forming pockets of absorbent nonwoven fabric. In order to function, it appears that these pockets would have to be opened during use to allow fluid to enter. However, based upon current understandings of vaginal pressures, it is not understood how the described structure could form such an opened volume.

U.S. Pat. No. 6,206,867. (Osborn) suggests that a desirable tampon has at least a portion of which is dry expanding to cover a significant portion of the vaginal interior immediately upon deployment. To address this desire, it discloses a tampon having a compressed central absorbent core having at least one flexible panel attached along a portion of the side surface of the core. The flexible panel appears to provide the “dry-expanding” function, and it extends outwardly from the core away from the point of attachment. The flexible panel contacts the inner surfaces of the vagina when the tampon is in place and purportedly directs fluid toward the absorbent core. The flexible panel is typically attached to the pledget prior to compression of the pledget to form the absorbent core and remains in an uncompressed state.

U.S. Pat. No. 5,817,077. (Foley et al.) discloses a method of preserving natural moisture of vaginal epithelial tissue while a using a tampon where the tampon has an initial capillary suction pressure at the outer surface of less than about 40. mm Hg. This allows the tampon to absorb vaginal secretions without substantially drying the vaginal epithelial tissue. The multiple cover layers can be used to increase the thickness of the cover material. While this represents a significant advancement in the art, this invention does not address by-pass leakage.

Additionally, U.S. Pat. No. 5,545,155. (Hseih et al.) discloses an external absorbent article that has a set of plates separated by spacer elements. The plates may be treated to affect wettability so that fluid will flow easily across the surface. Extending through the upper plate is a plurality of openings, which allow fluid to flow with little restriction into the space between the upper and lower plates. When the fluid flows downward in the z-direction from the upper plate to the lower plate, it will then flow laterally in the x- and y-directions. Therefore, an external absorbent article can contain fluid gushes, but it does not appear to address the problems relating in particular to intravaginal devices, such as a tampon.

Still others have created density differences within the absorbent structure of the tampon to try to encourage fluid transport within the tampon's absorbent structure. These density differences may allow the tampon to absorb somewhat more fluid, but premature leakage still occurs.

A further attempt to solve the problem of premature tampon leakage has been to create holes of different sizes within the tampon cover. The areas with the larger holes may absorb more fluid, but the areas with the smaller holes are limited in the amount of fluid that they can absorb, and premature leakage may still occur.

While the prior art is replete with examples of sanitary protection articles that capture bodily fluids both externally and intravaginally, these examples do not overcome the problem of premature failure often identified as by-pass leakage that commonly occurs while using internal sanitary protection devices. Many solutions to this problem have involved increasing the rate of expansion of a highly compressed absorbent article.

Therefore, a need exists for a method of capturing and storing intravaginal bodily fluid in such a manner that reduces premature leakage and utilizes the absorbent capacity of an intravaginal absorbent device.

SUMMARY OF THE INVENTION

In one aspect of the invention, a method is described for capturing bodily fluid intravaginally. The method involves providing an intravaginal device having at least one fluid transport element capable of interfacing with a body element to provide a substantially uninterrupted fluid conduit to a fluid storage element in fluid communication therewith. The distal portion of the at least one fluid transport element is capable of extending away from the fluid storage element. The fluid transport element is bendable about an axis substantially parallel to the longitudinal axis of the fluid storage element and the fluid transport element being positioned within a human vagina.

Intravaginal bodily fluid is exposed to the at least one transport element and is transported between the at least one transport element and the body element by inter-plate capillary action to the fluid storage element, where the fluid is stored.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As used herein in the Specification and the Claims, the term “bodily fluid” and variants thereof mean liquids that are produced by, secreted by, emanate from, and/or discharged from a human body.

As used herein in the Specification and the Claims, the term “fluids” and variants thereof relate to liquids, and especially bodily fluids.

As used herein in the Specification and the Claims, the term “sheet” and variants thereof relate to a portion of something that is thin in comparison to its length and breadth.

As used herein in the Specification and the Claims, the term “parallel plate” and variants thereof relate to a system of at least two relatively parallel sheets that are capable of moving fluids through inter-plate capillary action. The individual “plates” in the system may be flexible and/or resilient in order to move within their environment. However, they may be maintained in a substantially facing relationship with relatively constant separation at least in a localized portion of their structure (as compared with their relative length and width). Thus, two sheets could be fluted, but if the flutes are “nested”, the sheets would generally remain generally parallel in any given localized portion.

As used herein in the Specification and the Claims, the term “inter-plate capillary action” and variants thereof mean the movement of fluid due to a pressure difference across a liquid-air meniscus created within a gap between two substantially parallel plates. The two plates need not be held apart a specific distance, although they should be separable to allow fluid to move between them by inter-plate capillary action. A general equation providing the rise of a fluid between parallel plates is reported as:

$h = \frac{2\sigma*\cos\;\theta}{\rho*g*d}$

in which:

h is rise of fluid between plates

σ is the surface tension of fluid in contact w/plate

θ is contact angle

ρ is density

d is distance between plates, and

g is the gravitational constant

Therefore, as long as the contact angle, θ, is less than 90°, there will be some capillary attraction.

As used herein in the Specification and the Claims, the term “porous medium” and variants thereof relates to a connected 3-dimensional solid matrix with a highly ramified network of pores and pore throats in which fluids may flow.

As used herein, the term “separable plates” means any condition of separation of the first plate and the second plate, which allows fluid to move between the plates. This includes situations in which facing surfaces of adjacent first and second plates are touching one another in portions of or across substantially all of their facing surfaces. This also includes situations in which the facing surfaces of the adjacent first and second plates are separably joined together such that upon contact with fluid, the surfaces separate enough to provide for fluid to move between them. This further includes situations in which facing surfaces of adjacent first and second plates are joined together, as long as fluid may still move freely between the surfaces.

As used herein in the Specification and the Claims, the term “in fluid communication” and variants thereof relate to elements that are arranged and configured to allow fluid to move therebetween. The fluid movement may be by interfiber capillary movement, intrafiber capillary movement, osmotic pressure, interplate capillary action, mechanical channeling, and the like.

As used herein in the Specification and the Claims, the term “coupled” and variants thereof relate to the relationship between portions of an integral structure that are either portions of the same material (e.g., two portions of a folded sheet) or are materials that are joined together (e.g., two separate sheets that are bonded together).

As used herein in the Specification and the Claims, the term “fluid-permeable cover” and variants thereof relates to materials that cover or enclose surfaces of the device and reduce the ability of portions (e.g., fibers and the like) from becoming separated of the device and left behind upon removal. The term and variants thereof include, without limitation, sheet-like materials, such as apertured films and woven and non-woven fibrous webs, surface treatments, such as coatings or cover layers of integrating materials, such as binders and thermobondable fibers, and the like.

Referring to FIGS. 1 a. & 1 b, one embodiment of this invention provides an fluid management device 10 having a plurality of fluid transport elements 12 (four are shown in FIG. 1 a) in the form of flexible rods, preferably with a shaped cross-section as shown in FIG. 1 b.. These flexible provide a substantially continuous fluid path to the fluid storage element 14. The device may also include a withdrawal mechanism, such as a string 16. When inserted, the fluid transport elements 12 can create a substantially continuous fluid path in the notch 18 between the arms 20.

An alternate embodiment having a plurality of capillary tubes 12′ is illustrated in FIG. 2. These tubes 12′ also provide a substantially continuous fluid path to the fluid storage element 14′.

Yet another alternate embodiment, illustrated in FIGS. 3 a. & 3 b, provides an fluid management device 10 having at least one fluid transport element 12″ in fluid communication with a fluid storage element 14″ (FIGS. 3 a. & 3 b. show two fluid transport elements 12″ located on opposite sides of the fluid storage element 14″). The device may also include a fluid transfer layer 22 to move collected fluid about the fluid storage element 14″. The fluid transport element 12″ has at least one plate 24 that has a distal portion 26 that is capable of extending away from the fluid storage element 14″. When inserted, the at least one plate 24 can provide two surfaces that can interact with vaginal walls “W” to create two sets of parallel plates as shown in FIG. 4.

As mentioned above, the fluid management device 10 of the present invention may include a transfer or distribution layer 22. The transfer layer or distribution layer, if present, is generally positioned as an outer layer of the fluid storage element 14″, although it may in turn be enclosed by a fluid-pervious cover 28, and the transfer layer usually directly contacts the fluid storage element. If included, the transfer layer may be made of any known material that will take up fluid and then distribute and release it to an adjacent absorbent layer for storage. Transfer layers have a relatively open structure that allows for movement of fluid within the layer. Suitable materials for such transfer layers include fibrous webs, resilient foams, and the like.

The transfer layer provides a means of receiving bodily fluid from the fluid transport element and holding it until the fluid storage element has an opportunity to receive the fluid. The transfer layer is, preferably, more dense than the fluid-pervious cover layer and has a larger proportion of smaller pores than does the cover layer. These attributes allow the transfer layer to contain bodily fluid and hold it away from the outer side of the cover layer, thereby preventing the fluid from re-wetting the cover layer and its outer surface. However, the transfer layer is preferably not so dense as to prevent the passage of the fluid through the transfer layer and into the underlying fluid storage element.

The transfer layer may include various materials, including, for example, fibrous webs, resilient foams, and the like. The transfer layer may include cellulose fibers such as from wood pulp, single component or bicomponent fibers that include thermoplastic materials (such as, polyester, polypropylene, polyethylene, among others) in fiber or other forms, rayon, organic binders (such as, copolymers of vinyl, acrylic and/or other monomers that may be coated onto thermoplastic fibers or otherwise incorporated into the transfer layer) among other materials known to the art. The transfer layer may, for example, have-a basis weight in a range from about 40. gsm to about 120. gsm, a thickness in a range from about 0.5. mm to about 4. mm, a density in a range from about 0.03. g/cc to about 0.15. g/cc.

The mass of materials making up the transfer layer may be absorbent, although the materials themselves are not absorbent. Thus, transfer layers that are made of hydrophobic, nonabsorbent fibers may be able to accept large volumes of fluid into interfiber void spaces while the fibers themselves do not absorb any significant quantities of fluid. Likewise, open-celled foam structures that are made from nonabsorbent materials may also absorb fluid into the cells of the foam. The walls of the cells, however, do not absorb any fluid. The cumulative spaces within the transfer layer, i.e., the interfiber void spaces in the fibrous transfer layer or the open cells in the foam transfer layer, function much like a container to hold fluid.

Typically, transfer layer fibrous webs are made of resilient, nonabsorbent materials to provide void volume and to allow for free movement of fluid through the structure. Transfer layers that are made from webs of mostly absorbent fibers absorb the fluid as it enters the structure and do not distribute it throughout the rest of the structure as efficiently as webs containing non-absorbent materials. Transfer layer fibrous webs that include nonabsorbent materials are expected to provide void volume and to allow for more free movement of fluid through the structure. Examples of such materials include polypropylene, polyethylene, polyester, bicomponent materials, nylon and mixtures or combinations thereof. Alternative materials for transfer layers include apertured film; it can be any other nonwoven material, such as, foam or netting, which transports fluid and in combination with the cover, may provide masking of the fluid storage element.

A further alternate embodiment is shown in FIGS. 5 a-5 c. in which a intravaginal device 50 has at least one fluid transport element 52 in fluid communication with a fluid storage element 54 (FIGS. 5 a-5 c. show two fluid transport elements 52 located on opposite sides of the fluid storage element 54). The device may also include a withdrawal mechanism, such as a string 56. The fluid transport element has at least a first plate 58 and a second plate 60. The first and second plates combine to provide a set of parallel plates, and the fluid transport elements 52 are shown as extending radially away from the fluid storage element 54. Additional plates may also be incorporated into each fluid transport element 52.

The plates are arranged and configured to allow the introduction of bodily fluid 62 to separate a plate from adjacent plate(s) (FIG. 5 c). At least one opening 64 allows the introduction of bodily fluids 62. Optionally, one or more spacer elements 66 can be inserted to establish and to maintain space between adjacent plates.

FIG. 5 b. shows a pair of parallel plates prior to the introduction of a fluid. In this view, the facing surfaces of the adjacent plates 58, 60 are in contact. On the other hand, FIG. 5 c. shows the set of parallel plates separated by a bodily fluid 62, providing an inter-plate capillary gap 68 between the inwardly oriented surface 70 of the first plate 58 and the first surface 72 of the second plate 60. This inter-plate capillary gap 68 is sufficient to provide inter-plate capillary action to allow the fluid transport element 52 to acquire, to spread, and to move bodily fluids 62 from the vagina to the fluid storage element 54. The first plate 58 also has an outwardly oriented surface 74, and the second plate 60 also has an opposite surface 76.

In each of these embodiments, a distal portion 78 of the fluid transport element 52 is capable of extending away from the fluid storage element 54 and thereby creating a substantially uninterrupted fluid conduit from a fluid source to the fluid storage element.

The plates 58, 60 can be made of almost any hydrophobic or hydrophilic material, preferably sheet-like. The thickness of each plate is not critical. However, it can preferably be selected from the range of from about 0.005. to about 0.050. inch. The materials of construction and the thickness of the plates should be designed so that they are sufficiently stiff and/or resistant to wet collapse when exposed to fluid.

In particular, materials useful for forming the fluid transport element may have properties such as thermobondability to provide means to incorporate it into the fluid management device. A representative, non-limiting list of useful materials includes polyolefins, such as polypropylene and polyethylene; polyolefin copolymers, such as ethylenevinyl acetate (“EVA”), ethylene-propylene, ethyleneacrylates, and ethylene-acrylic acid and salts thereof; halogenated polymers; polyesters and polyester copolymers; polyamides and polyamide copolymers; polyurethanes and polyurethane copolymers; polystyrenes and polystyrene copolymers; and the like. The fluid transport element may also be micro-embossed or apertured. Examples of films having apertures include for example, three-dimensional apertured films, as disclosed in Thompson, U.S. Pat. No. 3,929,135, and Turi et al, U.S. Pat. No. 5,567,376, as well as two-dimensional reticulated film, such as that described in Kelly, U.S. Pat. No. 4,381,326.. FIGS. 6 a-6 c. illustrate three combinations of the apertured film of Thompson.

It may be helpful to keep the exposed surface of the fluid transport element as smooth as possible. It may also be helpful to provide it with a low coefficient of friction. These characteristics may provide at least two benefits: (1) the force required to insert the intravaginal device is reduced, and (2) it reduces the damage otherwise caused by scraping of soft, tender vaginal tissue during insertion, wearing and removal. Plates 58 and 60 may be made from the same material or alternately, plate 58 may be made from a different material than plate 60.

The parallel plates can have any physical structure to provide a resistance to fluid flow vector in the direction parallel to the inwardly oriented surface 70 of the first plate 58 and the first surface 72 of the second plate 60 that is less than the resistance to fluid flow vector in the direction perpendicular to the plates. Preferably, the plates are made from any relatively smooth material. Suitable materials include, without limitation, foil, waxed sheets, film, apertured film, and the like. For example fibrous or porous sheets may be coated with a substantially continuous coating to provide a film- or foil-like surface. Each plate does not need to be made of the same material as its corresponding parallel plate. For instance the first plate 58 could be an apertured film to allow fluid to enter and the second plate 60 could be a solid film to move fluid to the storage element. Of course, the parallel plates must be able to transport fluid between the two layers.

The fluid transport element 52 should be strong enough to prevent rupturing during handling, insertion, and removal and to withstand vaginal pressures during use.

It is preferable that the surface of at least one of the plates of the fluid transport element 52 be sufficiently wettable by the bodily fluids that the intravaginal device 50 is intended to collect (this results largely from a correlation of the surface energy of the plate surface and the bodily fluid(s)). Thus, the bodily fluid will easily wet the plate, and capillarity between the plates will draw these bodily fluids from a source to a fluid storage element that is in fluid communication with the fluid transport element.

Surface treatments can be used to modify the surface energy of the plates 58, 60. In a preferred embodiment a surfactant is applied to increase the wettability of the outer or inner surfaces of at least one plate. This will increase the rate at which the bodily fluids are drawn to and spread by plates, either between two plates or between a plate and the vaginal wall. The surfactant can be applied uniformly to either the inner or outer surfaces or it could be applied with varying coating weights in different regions.

A useful measure to determine the wettability of a plate surface is its contact angle with 1.0% saline. Preferably, the contact angle with 1.0% saline is less than about 90. degrees.

The spacer elements 66 can be separate elements applied to one or more of the plates, or they can be integral portions of a plate that extend away from one of the plate's major surfaces. A representative list of such separate spacer elements includes, without limitation, foamed materials such as polystyrene foam; particles such as beads and crystals; discontinuous material such as netting, thread, wax, adhesive, any discrete element that causes a separation between the plates and the like.

Integral spacer elements 66 can be thickened portions of the plate material or deformations of the plate material. A representative list of such an integral spacer element includes, without limitation, nubbles, embossments, corrugations, deformations, and the like. Included in this definition are surface treatments that permanently bond a secondary material to a surface of a first. One example of a deformation is provided as the sidewalls 80 of a “three-dimensional” polymeric apertured formed film material shown in FIGS. 6 a-6 c.. FIG. 6 a. shows the sidewalls 80 of inwardly facing surface 70 and the first surface 72 of the second plate 60 in facing relationship. FIG. 6 b. shows a second arrangement of the apertured film plates where the sidewalls 80 are nested. FIG. 6 c. illustrates a third configuration of the apertured film plates where the sidewalls 80 are on the inwardly facing surface 70 of the first plate 58, and sidewalls 80 are on the opposite surface 76 of the second plate 60.

In another example, shown in FIG. 7, the spacer elements are nubbles 82 extending from the inward surface 70 of the first plate 58 and resting on the first surface 72 of the second plate 60.

In order to maintain stability against sliding of the plates with respect to each other and changing of the space between them, it is acceptable, and may be preferable, to secure some local areas of contact between the spacer elements 66 and the adjacent plate or even between spacer elements 66 of two adjacent plates. The plates may be secured through means known to those of ordinary skill in the art. A representative list of such securing means includes, without limitation, thermobonding, adhering, crimping, embossing, ultrasonic bonding or welding, and the like. The adhesive may be applied between the spacer elements and the first and second plates. Preferably, the adhesive is wettable.

The at least one opening 64 can be at the edge of the plates, e.g., edges of adjacent plates are separated or plates themselves may have at least one opening. The openings need not be uniform. For example, one opening 64 may be located at the edge of the plates and a plurality of smaller openings or apertures 84 can be distributed throughout one or more plate. Preferably, each plate has a plurality of openings distributed throughout. An example of openings distributed throughout is an apertured film. The distribution can be uniform or arranged to provide regions of higher open area and regions of lower open area.

A plurality of openings or apertures 84 may extend through at least one of the first and second plates 58, 60. These apertures 84 may extend completely through the plate and may be present in both of the plates. The apertures 84 allow fluid that contacts the outward surface 74 of the first plate 58 or the opposite surface 76 of the second plate 60 to flow into the inter-plate capillary gap 68 between the plates with as little restriction as possible. In the example of apertured film, it is preferred that the total surface area of the plate occupied by the openings is from about 5% to preferably about 50%. More preferably, it will be from about 25% to about 45%. Having this much open area formed in a plate will allow fluid that is deposited on that plate to easily flow into the inter-plate capillary gap 68.

It is preferable that any individual opening 64, 84 is large enough to easily pass any highly viscous material, including menstrual fluid. While the geometry of the openings is not critical, the opening 64, 84 should be sized sufficient to allow easy passage of non-absorbable material. If the apertures 84 are not circular, then the measurement should be made across the narrowest part of the opening, which would be most restrictive to the flow of non-absorbable material.

In the example of unapertured film that has an opening 64 at the ends of the plates 58, 60, the size of the opening 64 is a result of the fluid's ability to separate the plates.

It is preferred that the apertures 84 are large enough to let viscous fluid pass through but not too large to create too rough of a surface as to compromise the wearer's comfort. A preferred aperture 84 is circular and is between 10. mils and 40 mils in diameter. Most preferably it is between 18. mils and 27. mils.

Open area may be determined by using image analysis to measure the relative percentages of apertured and unapertured, or land, areas. Essentially image analysis converts an optical image from a light microscope into an electronic signal suitable for processing. An electronic beam scans the image, line-by-line. As each line is scanned, an output signal changes according to illumination. White areas produce a relatively high voltage and black areas a relatively low voltage. An image of the apertured formed film is produced and, in that image, the holes are white, while the solid areas of thermoplastic material are at various levels of gray. The more dense the solid area, the darker the gray area produced. Each line of the image that is measured is divided into sampling points or pixels. The following equipment can be used to carry out the analysis described above: a Quantimet Q520. Image Analyzer (with v. 5.02B software and Grey Store Option), sold by LEICA/Cambridge Instruments Ltd., in conjunction with an Olympus SZH Microscope with a transmitted light base, a plan 1.0× objective, and a 2.50× eyepiece. The image can be produced with a DAGE MTI CCD72. video camera.

A representative piece of each material to be analyzed is placed on the microscope stage and sharply imaged on the video screen at a microscope zoom setting of 10×. The open area is determined from field measurements of representative areas. The Quantimet program output reports mean value and standard deviation for each sample.

Referring to FIGS. 8 a-18, the first and second plates 58, 60 may be separate elements (i.e, adjacent to each other but not necessarily joined) or they may be extensions of the same sheet-like material, e.g., formed by a fold in a sheet of material (as shown in FIGS. 8 a-8 e). In such a folded embodiment, the material is folded to form a pleat with the first and second plates facing each other.

A preferred embodiment with pleats is shown in FIGS. 8 a-8 e, where the pleats 86 are folds in the fluid-pervious cover material 88. The pleats 86 create plates that are bendable about an infinite number of bending axes (b_(1-i)-b_(1-i)) that are substantially parallel to the longitudinal axis (X-X) of the product, which longitudinal axis extends through the insertion end 90 and withdrawal end 92. These bending axes allow the plates to wrap around the product, either partially or completely. One such bending axis (b₁-b₁) is shown in FIG. 8 b.

The fluid transport element 52 is in fluid communication with the fluid storage element 54 and directs fluid from the vagina to the storage element 54. Generally, fluid will be directed from each fluid transport element 52 to a particular region of the fluid storage element associated with that fluid transport element. Thus, if the device has only one fluid transport element 52, the fluid will contact the fluid storage element in one interface 94.

Therefore, additional fluid transport elements 52 directing fluid to additional locations of the fluid storage element 54 will improve the efficient usage of the fluid storage element 54. For example, two fluid transport elements 52 could be directed to opposite sides of the fluid storage element 54, as shown in FIGS. 5 a-5 c.. Each additional fluid storage element 5 can direct fluid to additional interface locations 94 of the fluid storage element 54. For example, four evenly spaced fluid transport elements 52 allow fluid to be directed to each quarter of the fluid storage element 54 surface as shown in FIGS. 8 a-8 e.. Five or more elements would provide even more direct access. This can allow the fluid to contact the fluid storage element 54 uniformly and help to prevent or reduce local saturation of the fluid storage element 54.

While the above description provides for direct fluid communication between a fluid transport element 52 and the fluid storage element 54, direct fluid contact is not necessary. There can be fluid communication through an intermediate element, such as a porous medium (e.g., a foam or fibrous structure), a hollow tube, and the like.

Enlarging the area of the interface 94 between the fluid transport element 52 and fluid storage element 54 can also help to maximize the fluid communication. For example, elongating the interface by increasing the length of the fluid transport element 52 allows more fluid to flow into the fluid storage element 54.

The fluid transport element 52 may extend in any orientation from the surface of the fluid storage element 54. It is not necessary for the fluid transport element to be on the surface of the fluid storage element.

The inter-plate capillary gap 68 formed by first and second plates 58, 60 can terminate at the interface 94 or can extend into and/or through the fluid storage element 54. An example of the fluid transport element 52 extending into the fluid storage element 54 is shown in FIG. 7. The parallel plates can have additional layers on top of them as long as these additional layers allow fluid to enter the plates. The first and second plates may be arranged such that they can be extended in a plane that is parallel to, or even extending through, the longitudinal axis of the device (e.g., FIGS. 9, 10 a, 10 b, and 11). Alternately, they may also be arranged such that they can be extended in a plane that is perpendicular to the longitudinal axis of the device, or in any orientation between these extremes (not shown).

The first and second plates 58, 60 can end at the boundary of the fluid transport element 52 or can extend into the fluid storage element 54. FIG. 11 shows two sets of parallel plates extending into the storage element. The parallel plates can have additional layers on top of them as long as these additional layers allow fluid to enter the plates.

The fluid transport element 52 may be formed to extend from the surface of the fluid storage element 54 as in FIG. 5 a-5 c.. In an alternative embodiment, the withdrawal string 56 could be replaced by a pair or another combination of ribbon-like parallel plates (not shown).

The fluid transport element 52 can be made in any convenient shape, including semicircular, triangular, square, hourglass etc. Additionally the two plates of the element do not have to be completely coextensive, as long as they are at least partially in a facing relationship.

The parallel plates forming the fluid transport element can be of any flexibility as long as the material is able to transport fluid to the fluid storage element while the device is in use. It is also preferable that the fluid transport element be sufficiently flexible to provide the user with comfort while inserting, wearing and removing the device.

Parallel plates can be held in close proximity to the storage element in a variety of ways including directly or indirectly via an additional element to the storage element. A variety of methods can be used to attach the fluid transport is element 52 including but not limited to heat, adhesive, ultrasonics, sewing, and mechanically engaging the fluid storage element 54. An example of a heat-sealed attachment 96 is shown in FIG. 8 a.

The fluid transport element(s) 52 can be attached at the sides, insertion end 90, and/or withdrawal end 92 of the intravaginal device 50. Additionally, the fluid transport element(s) 52 may be attached to themselves and not to the storage element as in a parallel plates bag type covering of the storage element. The parallel plates could also be attached to the withdrawal string 56. Additional means of attachment are disclosed in the commonly-assigned, copending patent applications entitled “Intravaginal Device with Fluid Acquisition Plates” (U.S. Ser. No. 60/572054;), “Intravaginal Device with Fluid Acquisition Plates and Method of Making” (U.S. Ser. No. 60/572055;), both filed on May 14, 2004, the contents of which are herein incorporated by reference.

Multiple fluid transport elements can be layered on top of each other or placed next to each other. FIG. 12 shows a plurality of fluid transport elements 52 extending from the sides of the storage element 54 in a plane perpendicular to the axial direction thereof. These fluid transport elements 52 can be a variety of lengths and can be on part or the entire surface.

A further alternate embodiment, shown in FIG. 13, has one continuous plate 58′ rolled up on itself to form a series of convolutedly wound plates, each having a first surface and a second surface. The first surface of the plate in one winding of the device is disposed and maintained in facing relationship with the second surface of an adjacent winding. The first surface is also capable of separating from the second surface sufficiently to provide inter-plate capillary action. In this embodiment, the inner layers of the winding would also act to store fluid, allowing them to function as a fluid storage element.

During use, fluid transport element(s) 12, 52 can take on many configurations within the vagina. For example, a fluid transport element 12″ may extend into the vagina away from the fluid storage element 14″, as shown in FIG. 4. Alternatively, the fluid transport element(s) 52 may remain wound about the fluid storage element 54, contacting the vaginal wall “W” only through the outwardly oriented surface 74 (FIG. 14). In a further alternative embodiment, the fluid transport element(s) 52 may be substantially contained within the fluid storage element 54 and thus may not be in contact with the vaginal walls at all. Thus, the fluid transport element(s) 52 may be completely contained within the fluid storage element, or it may extend to an outer surface of the fluid storage element, as shown in FIG. 9. in which the fluid transport element 52 is disposed only within the fluid storage element 54). Additionally, as discussed above in reference to FIG. 11, the fluid transport element(s) may extend beyond an outer surface of the fluid storage element 54.

The fluid storage element can be any convenient shape including cylindrical, cup like, hourglass, spherical, etc. It can be an absorbent or a fluid collection device. It can be in separate sections with the fluid transport element(s) 52 bridging or connecting the sections. FIGS. 15 a. and 15 b. shows a plurality of storage elements connected by two fluid transport elements 52″. FIG. 16 shows two sides of the same unified storage element 54″ bridged by a fluid transport element 52″.

The fluid storage element 54 can be made of any composition known in the art, such as compressed fibrous webs, rolled goods, foam etc. The storage element can be made of any material known in the art such as cotton, rayon, polyester, superabsorbent material, etc.

In one preferred embodiment, the fluid storage element 54 is an absorbent tampon 50. Absorbent tampons are usually substantially cylindrical masses of compressed absorbent material having a central axis and a radius that defines the outer circumferential surface of the tampon. Such tampons are disclosed in e.g., Haas, U.S. Pat. No. 1,926,900;. Dostal, U.S. Pat. No. 3,811,445;. Wolff, U.S. Pat. No. 3,422,496;. Friese et al., U.S. Pat. No. 6,310,296;. Leutwyler et al., U.S. Pat. No. 5,911,712, Truman, U.S. Pat. No. 3,983,875;. Agyapong et al., U.S. Pat. No. 6,554,814. Tampons also usually include a cover (which may include or be replaced by another surface treatment) and a withdrawal string or other removal mechanism.

Absorbent materials useful in the formation of the absorbent body include fiber, foam, superabsorbent, hydrogels, and the like. Preferred absorbent material for the present invention includes foam and fiber. Absorbent foams may include hydrophilic foams, foams that are readily wetted by aqueous fluids as well as foams in which the cell walls that form the foam themselves absorb fluid.

Fibers may be selected from cellulosic fiber, including natural fibers (such as cotton, wood pulp, jute, and the like) and synthetic fibers (such as regenerated cellulose, cellulose nitrate, cellulose acetate, rayon, polyester, polyvinyl alcohol, polyolefin, polyamine, polyamide, polyacrylonitrile, and the like).

The fluid storage element may also be in the form of a collection cup. Examples of such devices are disclosed in Zoller, U.S. Pat. No. 3,845,766. and Contente et al., U.S. Pat. No. 5,295,984.. Collection devices are designed to assume a normally open, concave configuration, with an open side facing a user's cervix. The collection devices may be folded, or otherwise manipulated, to facilitate insertion into the vaginal canal.

A withdrawal mechanism, such as withdrawal string 16, 56, is preferably joined to the fluid management device 10, 50 for removal after use. The withdrawal mechanism is preferably joined to at least the fluid storage element 14, 54 and 10 extends beyond at least its withdrawal end 92. Any of the withdrawal strings currently known in the art may be used as a suitable withdrawal mechanism, including without limitation, braided (or twisted) cord, yarn, etc. In addition, the withdrawal mechanism can take on other forms such as a ribbon, loop, tab, or the like (including combinations of currently used mechanisms and these other forms). For example, several ribbons may be twisted or braided to provide parallel plates structures.

Tampons are generally categorized in two classes: applicator tampons and digital tampons, and a certain amount of dimensional stability is useful for each type of tampon. Applicator tampons use a relatively rigid device to contain and protect the tampon prior to use. To insert the tampon into a body cavity, the applicator containing the tampon is partially inserted into the body cavity, and the tampon can be expelled from the applicator into the body cavity. In contrast, digital tampons do not have an applicator to help guide them into the body cavity and require sufficient column strength to allow insertion without using an applicator.

While the applicator tampon is protected by the rigid applicator device and the applicator tampon need not as have high a degree of column strength as a digital tampon, applicator tampons do require dimensional stability (especially radial) to be acceptable for use. This dimensional stability provides assurance, for example, that the tampon will not prematurely grow and split its packaging material or become wedged in a tampon applicator.

Further, the fluid management device can be collapsed for packaging and insertion. For example, at least a portion of a major surface of the fluid transport element 52, such as the outwardly oriented surface 74, may be in contact with at least a portion of an outer surface of the fluid storage element 54. This can be achieved by wrapping the fluid transport element(s) around the fluid storage element 54 (as shown in FIG. 8 b). Alternatively, the fluid transport element(s) 52 may be folded or pleated (e.g., in an accordion-like manner as shown in FIG. 17) against the fluid storage element 54. The thus-compacted device can then be packaged, (e.g., within an applicator or alone in a wrapper). FIG. 18 shows a wrapped tampon within an applicator 98 (in phantom).

In this invention, the intravaginal device can be used to capture or store bodily fluid. In particular, a method is provided for a capturing bodily fluid management device, the device having at least one fluid transport element capable of interfacing with a body element to provide a substantially uninterrupted fluid conduit to a fluid storage element in fluid communication therewith; wherein a distal portion 78 of the at least one fluid transport element 52 is capable of extending away from the fluid storage element 54.

Further, the invention provides a method of using a plurality of tampons during a period of menstruation. The user can obtain an intravaginal device, such as a tampon, as described hereinabove. She can position a first tampon within her vaginal canal while maintaining at least a portion of a major surface of the fluid transport element in contact with at least a portion of an outer surface of the fluid storage element. The tampon can be left to collect a first volume of vaginal discharge while holding the first tampon in position. She can then remove the first tampon and subsequently dispose of it. The user can then obtain a second, similar tampon to replace the first. These steps are performed during a woman's period of menstruation, and they can be repeated as often as necessary.

During the insertion of the tampon, the user may choose to manipulate the tampon 50 to unwrap or allow a distal portion 78 of the at least one fluid transport element from the outer surface of the fluid storage element 54. In this manner, the outwardly oriented surface 74 of the first plate 58 and the opposite surface 76 of the second plate 60 may both contact the vaginal walls “W”, as shown in FIG. 4. Alternately, the user may insert the tampon 50 without significantly disturbing the at least one fluid transport element 52, and the element will more likely remain as it was packaged. For example, a tampon having a convolutedly wrapped fluid transport element may leave it in that position, as shown in FIG. 14.

Alternately, this invention provides a method for storage of bodily fluids. The method provides a fluid management device capable of storing bodily fluid intravaginally, the method providing a fluid storage element positioned within a human vagina and having a longitudinal axis and at least one fluid transport element in fluid communication with the body element, the at least one fluid transport element bendable about an axis substantially parallel to the longitudinal axis of the fluid storage element, whereby bodily fluid within the human vagina is exposed to the fluid transport element and is transported between the at least one fluid transport element and the body element interplate capillary action to the fluid storage element where the fluid is stored.
